Christian answer:Jesus celebrated all the Jewish festivals, so if you truly want to imitate the son of God it wouldn't hurt. Many Jewish festivals foreshadow the arrival of the Messiah, so by celebrating these festivals you are celebrating the fact that the Messiah has arrived and that through his your sins are forgiven.Jewish answer:The only reason a Christian might want to observe a Jewish festival would be to understand today's Jews a little better, and maybe some misconceptions might disappear. Otherwise, there is no spiritual reason.

Pontius Pilate was the Roman governor of Judea. His family background was from south-central Italy, so his traditions were entirely Roman, not Jewish. As governor of Judea, he had to be aware of the major Jewish festivals, because they were times of heightened tension and civil unrest in Jerusalem -- simply because of the pilgrimages to Jerusalem taken by a large fraction of the Jewish population on the festivals. He would likely have "observed" the festivals by putting his troops on heightened alert.
